D. Cardinal, 2022

Note: As of March, 2022, there is a bug in the 2021 version of Matlab, so that the images don't properly render in the LiveScript. So you can either: run this as a Script (using Right-Click from the file tree), or snag an early release of 2022a, or simply look at the HTML version that we've exported from a properly running system.

Initialize ISET and Docker

ieInit;
if ~piDockerExists, piDockerConfig; end

useScene = 'cornell_box'; % one of our default scenes
raysPerPixel = 96;

fprintf('Sensor Size: %d, rayPP %d, resolution %d\n',...
    sensorSize,raysPerPixel,sensorResolution);
Sensor Size: 6, rayPP 96, resolution 400

Read the selected Scene and add a Light

Read 7 materials.
Read 0 textures.
***Scene parsed.
lightName = 'from camera';

recipeSet(thisR,'lights', ourLight,'add');

Set render quality

% Set resolution for speed or quality.
thisR.set('film resolution',[sensorResolution sensorResolution]);  % 2 is high res. 0.25 for speed
thisR.set('rays per pixel',raysPerPixel);                      % 128 for high quality
% Pick out a bit of the image to look at.  Middle dimension is up.
% Third dimension is z.  For the chess set we use a from/to that put the ruler in the

Determine the range of object depths in our scene

Note: Getting depth will use pinhole optics, but we use an omni camera with lenses for the rest.

depthRange = thisR.get('depth range');

exr2bin done.
%depthRange = [0.1674, 3.3153];  % Chess set distances in meters

Create cameras that use each lens

We get a list of all our lenses, then iterate over it creating a camera object using that lens, and render the same scene through each of them.

lensFiles = lensC.list('quiet', true);
images = []; % our output images
for ii = 1:numel(lensFiles)
    lensFileName = lensFiles(ii).name;
    lensFile = fullfile(lensFiles(ii).folder, lensFileName);
    fprintf('Using lens #%d: %s\n',ii, lensFile);
    thisR.camera = piCameraCreate('omni','lensFile',lensFile);
    thisR.set('focal distance',mean(depthRange));
    % depending on the film size we'll get
    % different fields of view
    thisR.set('film diagonal',sensorSize);

Render and display

piWrite(thisR);

try

oi = piRender(thisR,'render type',{'radiance', 'depth'});

oi = oiSet(oi,'name',sprintf('Lens: %s ',lensFileName));

% get a viewable version of our optical image:

img = oiShowImage(oi,-1);

% Load our lens so we can view it

lenses{ii} = lensC('filename', lensFile);

% Set some headers per leans

fprintf('----------------------------\n');

fprintf('Rendered using: %s, with focal length: %05.1f',lensFileName,lenses{ii}.focalLength);

% subplot(2,1,1);

% It would be great if this could draw into a subplot. Help!

lenses{ii}.draw;

images{ii} = img; % for creating a montage

f = figure('Name',lensFileName,'MenuBar','none','ToolBar','none');

% Once the lens can draw into a subplot, we can show the sample

% output next to it

%subplot(2,1,2);

imshow(img,'Border','tight');

drawnow; %doesn't seem to help, but who knows?

fprintf('----------------------------\n');
